win 10 update leaves vertical pink line on screen

today i applied latest win 10 update and now i have a vertical pink line on screen, it remains on every screen. i have tried these fixes

Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software

BUT i still have the line on screen.

 

Windows 10 wont update


Have you tried the second step?

(Searching for the error message e.g.

windows update database corrupt

is also a useful approach- e.g. finds
Win 10 Update Database Corruption Solved - Windows 10 Forums
- where the next step is the one I suggested above).
